摘　　要：利用异氰酸根与偏苯三甲酸酐反应合成了端羧基聚(氨酯-酰亚胺)(PUI)材料,研究了反应时间的影响,并利用红外光谱和核磁共振氢谱对结果进行了表征。结果表明,通过逐步升温法,可以制备PUI材料。用差示扫描量热法和热失重法研究了材料的热学性能。The carboxyl terminated poly（ urethane imide）（ PUI） material was synthesized by the reaction of isocyanate with trimellitic anhydride. The influence of reaction time was studied and the results were characterized by IR spectrum and ^1 H-NMR. The results showed that PUI material can be prepared by stepwise heating up method. The thermal properties of the materials were studied by differential scanning calorimetry and thermal retransmission.
